The Chiefs started the 2011 season 0-3, only to win four straight and take first place in the AFC West.

However, Haley and the Chiefs gave away the top spot in the AFC after back-to-back home losses to the previously winless Miami Dolphins and the Denver Broncos. The Chiefs are currently in last place in the AFC West and hold a 5-8 record.

Haley replaced Herman Edwards in 2009 after Edwards lost 23 of his last 25 games to end his tenure as a Chief. Haley compiled a 4-12 record in his first year with the Chiefs. The following season, Haley helped the Chiefs put together the best turnaround in franchise history as the Chiefs stunned the world, winning 10 games and took the AFC West. The Chiefs were 19-27 under Haley in almost three complete seasons.

Expect Pioli and owner Clark Hunt to seek a big-name coach to take over the Chiefs franchise. St. Louis Rams offensive coordinator Josh McDaniels is a hot candidate due to the relationship between himself and Pioli with the New England Patriots.

However, it should be noted that Jeff Fisher, who had a lot of success in the AFC with the Tennessee Titans, is also a viable option to become the next head coach of the Kansas City Chiefs.

When this is all said and done, there's a chance that Crennel returns to become the primary head coach of the football team and earn his second chance at being a head coach.
